Original application filed July 25, 1910, Serial No. 573,807. Dividedand this application filed October 6,

T 0 all whom it may concern:

Be it known that I, WILLIAM SCHMIDT, a citizen of the United States,residing at Cincinnati, Ohio, have invented certain new and usefulImprovements in Metallic VVindew-Sash, of which the following is aspecification.

My present invention relates to improve ments in metallic windowconstruction, being a division of an application filed by me on the 25thday of July, 1910, #573,807, and has for its object to provide a simple,economical and efficient manner of removably securing the pane in place,and the invention comprises the novel features of constructionhereinafter described and particularly pointed out in the appendedclaims.

A sash constructed in accordance with my invention is illustrated in theaccompanying drawings, in which:

Figure l is a front view of a sufficient Fig. 2 is a sectional view online 22, and Fig. 3 is a section on line 33.

In this drawing, the numeral 4: designates the lower rail or bar of thesash, and 5 one of the side bars or rails. These are formed each of asingle piece of sheet metal bent into the shape shown, and with theedges folded or interlocked, as shown at 6. They are of identical shapein cross section except on their outer faces, where they are shaped toconform'to the portion of the frame with which they co-act, the bottomrail at having a groove 4? adapted to co-act with a suitably shaped sillmember to produce a weatherproof joint, and the side rail 5 having agroove or channel adapted to co-act with the guiding rib of the side ofthe window frame for guiding the sash in its vertical movement.

In order that the glass may be readily, firmly and yet removably held inplace, each sash bar is provided with an inclined portion 7 extendingfrom the seat 8 for the edge of the glass to a transverse shoulder 9,and against this portion 7 and shoulder 9 rests a hollow removablesecuring strip 10 which Serial No. 585,708.

has opposite parallel walls 10 and 10 other parallel walls 10 and 10 anda wall 10 perpendicular to the wall 10 the wall 10 being adapted toretain the glass and the walls 10 and 10 to coact with the seats 7 and9. The strip 10 is secured in place by set screws 11 which pass throughthe hollow securing strip 10 and the portion 7 and engaging abar 12having suitable threaded openings for the screws and riveted to theinner face of the said inclined portion 7.

In order to enable the screws to be screwed in tightly to hold thesecuring strip firmly in place without danger of crushing or distortingthe securing strip, the body of each screw is made larger than thethreaded portion which provides a shoulder 11 for bearing against theinner inclined wall of the securing strip when the screw is screwedhome.

Having thus described my invention what I claim is: I

l. A hollow sash bar having a permanent glass holding flange and seat,and an inclined portion adjacent said seat, and a hollow securing striphaving a correspondingly inclined portion, and securing screws passingthrough said hollow strip, said screws having shoulders for bearingagainst said inclined portion, substantially as described.

A hollow sash bar having a permanent glass holding flange and seatand an inclined portion adjacent said seat, a hollow securing striphaving a correspondingly inclined portion, securing screws passingthrough said hollow strip, said screws having shoulders for bearingagainst said inclined portion, and a reinforcing bar secured to theinner face of said inclined portion of the sash bar with which the endsof said screws engage, substantially as described.
